Yes, I do own an Intel dual core laptop

by dfichtner Jul 6, 2006 8:59AM PDT

Yes, actually, I recently purchased an HP dual-core intel HP DV2000 laptop/notebook. You might have seen that I had ordered an AMD version, but I cancelled it after the lackluster performance reports. I picked up a good deal on an Intel version of the same machine which went on sale at CompUSA.

I have been playing around with it, and although it's nice, and I can utilize the two cores doing a virus scan or while crunching video, 90% of the time, it's not that big of a deal to me. I am not under age 18, as you are. I own a powerful desktop and don't need my notebook to do more than 2 things at once.

Folks, the dual-core thing isn't THAT incredible. My advice stands -- pick up a bargain on a single-core machine, and you'll be just fine for 99% of notebook tasks. I was speaking to people who had to buy a notebook now. If you can wait, go ahead and do it.

By the way the dual-cores are definately hotter! Be it AMD or Intel.

My idea is ...

that once you had an experience with a dual-core processor, never you want to return in the past with a slowly single-core processor. Doing many things at the sametime is only too cool !

And I strongly don't recommend to get a single-core for the same reasons that I explained in your last post.

I agree

by mtf612 Jul 6, 2006 5:38PM PDT

My laptop has a 3.8 ghz 2mb l2 cache processor and it NEVER jumps over 30 % even during Half life 2 and CSS battles. So I have decided Im not gonna jump on the dual core bandwagon for a little bit.

Your P4

by Ghost26-20878886633866019035262628200812 Jul 7, 2006 5:50AM PDT

Your Pentium 4 has the hyper-threading technology which is a "simulation" of running on a dual-core. The dual-core will be better because it is entirely two cores that are running at the same time ( in games, only one core is running, the other pass in C3 state ( sleep mode if you want ).

So you have a little bit less performances than a dual-core. I know : my aunt own a Pentium 4 3.0 Ghz and it has the HT technology and performances are better on my laptop ( 1.66 GHz Core Duo ), but the HT delivers similar performances to a dual-core. In the task manager, you see two parts, one for the processor and the other for the Hyper-Threading. If the task manager see two parts, it's because the HT is "like" a dual-core, but it isn't. Hyper-threading, officially called Hyper-Threading Technology (HTT), is Intel's trademark for their implementation of the simultaneous multithreading technology on the Pentium 4 microarchitecture. It is basically a more advanced form of Super-threading that debuted on the Intel Xeon processors and was later added to Pentium 4 processors. The technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss.

For more details : http://en.wikipedia.org/wiki/Hyper-Threading

And the battery life is exceptional on the dual-core ! You don't know the pleasure to run it for a long time outside the house

So without you decided it, you own a dual-core ! ( a 3/4 dual-core because of the HT ).

Hyperthreading is "Hype"

by dfichtner Jul 14, 2006 6:10AM PDT

Ghost, I suggest you take a look at the exposed hyper surrounding hyperthreading:

Nice link

by Ghost26-20878886633866019035262628200812 Jul 14, 2006 11:42AM PDT

It almost what I said.

The link contains very good informations.

You missed the last paragraph

by dfichtner Jul 15, 2006 3:00PM PDT

"What are the downsides?

Not all software works well with hyper-threading. It can slow some software down -- including, to Intel's chagrin, most current benchmark software -- and quite a lot shows little or no improvement. Also, because Hyper-threading makes a lot more of the chip work a lot harder it increases power consumption and thus heat dissipation, stresses cache usage more, and so on."

Should I understand something ? Do I said something wrong ? Lol ! I really don't understand. I think I was clear on the HTT : it's a simulation of a dual-core processor. If I'm wrong, please, correct me ! I love to learn new things

I agree with you on the last paragraph. Evey technology has its downsides...

I Wonder

I wonder how good a Core Duo with HT Technology would be...

You don't need to have the HTT.

by Ghost26-20878886633866019035262628200812 Jul 14, 2006 11:46AM PDT

You don't have to have this technology anymore because in the Core Duo you have two cores running at the same times. You don't need the simulation of two cores of the HTT because you have two phisic cores.

So it is totally useless.
